In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)
Is there a way to redirect all stdout to a file implicitly - like defining stdout=/home/me/process.log - so that all "echo" commands in several scripts/subscripts are written to that file; instead of having to edit all scripts to redirect the "echo" (e.g. echo 'This is a test ' >>... (1 Reply)

Hi everybody,
I am trying to do the thing you see in the title, and I can't simply do
a=$(svn up)
echo $a
because the program (svn) gives output on lots of lines and in the variable the output is stored on only one line (resulting in a horribly formatted text). Any tips?
Thanks,... (2 Replies)
Hello,
I have a script (videostream.sh) which invokes the GStreamer command-line tool gst-launch with all the correct command line parameters. When I invoke this program, I add the '&' character at the end to make it a background task, so that my script can complete and exit, i.e.

I have a C program that continously outputs info to stdout. The problem is that I am redirecting the stdout and stderr to a file and stdout is written at the end of the problem rather than continously to the file. This could be a problem if for example the program is killed and the stdout output is... (3 Replies)
Hello,
I'm strugling with some redirecting and all help is apreciated.
The following program is working as expected, but the result of the AT command doesn't go to any file.

hi,
OK. I am writing a bash script, and it is almost working for me.
Problem 1: I currently have stout sent to a file (stout.miRNA.bash.$date_formatted) which I would like to have work inside my loop, but when I move it, it just prints to the screen.
Problem 2: I have a second file... (18 Replies)

Date::Parse(3) User Contributed Perl Documentation Date::Parse(3)NAME
Date::Parse - Parse date strings into time values
SYNOPSIS
use Date::Parse;
$time = str2time($date);
($ss,$mm,$hh,$day,$month,$year,$zone) = strptime($date);
DESCRIPTION
"Date::Parse" provides two routines for parsing date strings into time values.
str2time(DATE [, ZONE])
"str2time" parses "DATE" and returns a unix time value, or undef upon failure. "ZONE", if given, specifies the timezone to assume when
parsing if the date string does not specify a timezone.
strptime(DATE [, ZONE])
"strptime" takes the same arguments as str2time but returns an array of values "($ss,$mm,$hh,$day,$month,$year,$zone)". Elements are
only defined if they could be extracted from the date string. The $zone element is the timezone offset in seconds from GMT. An empty
array is returned upon failure.
MULTI-LANGUAGE SUPPORT
Date::Parse is capable of parsing dates in several languages, these include English, French, German and Italian.
$lang = Date::Language->new('German');
$lang->str2time("25 Jun 1996 21:09:55 +0100");
EXAMPLE DATES
Below is a sample list of dates that are known to be parsable with Date::Parse
1995:01:24T09:08:17.1823213 ISO-8601
1995-01-24T09:08:17.1823213
Wed, 16 Jun 94 07:29:35 CST Comma and day name are optional
Thu, 13 Oct 94 10:13:13 -0700
Wed, 9 Nov 1994 09:50:32 -0500 (EST) Text in ()'s will be ignored.
21 dec 17:05 Will be parsed in the current time zone
21-dec 17:05
21/dec 17:05
21/dec/93 17:05
1999 10:02:18 "GMT"
16 Nov 94 22:28:20 PST
LIMITATION
Date::Parse uses Time::Local internally, so is limited to only parsing dates which result in valid values for Time::Local::timelocal. This
generally means dates between 1901-12-17 00:00:00 GMT and 2038-01-16 23:59:59 GMT
BUGS
When both the month and the date are specified in the date as numbers they are always parsed assuming that the month number comes before
the date. This is the usual format used in American dates.
The reason why it is like this and not dynamic is that it must be deterministic. Several people have suggested using the current locale,
but this will not work as the date being parsed may not be in the format of the current locale.
My plans to address this, which will be in a future release, is to allow the programmer to state what order they want these values parsed
in.
